Hello!
Background: In the Kent District Library District (MI) 9 of the 18 branches have Local History Rooms. The physical building (including the LHRoom) is owned by the city/town, as are the Local History contents/collections, while the public library materials are owned by the library district.
The Local History collections are grown by local donations, and overseen by volunteers, who may or may not be library staff.
The ownership of the collections is exceedingly murky, as there may be no paperwork generated by the city/town when items are donated. Also, cataloging of the collections may/may not exist, or exists on volunteers' personal laptops.
Question: Are there other examples of this relationship across the country that you might be aware of?
